Types of validity

Face validity

Does it pass the intuition test?

Ecological validity:

The extent to which the measure generalizes to the real world and natural settings, not just in a lab

Predictive validity:

How the measure predicts later important elements

Internal validity:

How a measure consistent precedes and predicts the effect it ought to cause

Convergent validity:

How well the measure relates to an established method of measuring the construct (shown by a strong relationship between the scores obtained from two different methods of measuring the same construct

Divergent validity:

How distinct the measure is from an established method of measuring something else

Construct validity:

Demonstrated when scores obtained from a measurement behave exactly the same as the variable itself

Concurrent validity:

When scores obtained from a new measure are directly elated to scores obtained from a more established measure of the same variable
